SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 336,118, dated February 16, 1886.

Application filed December ll, 1885. Serial No. 185,403.

To all whom it may concern.-

Be it known that l, JosEPH V. KING, a citizen of the United States, residing at Roberts, in the county of Ford and State of Illinois, haveinvented a new and useful Improvement in Seal-Locks, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in seal-locks; and the novelty consists of the peculiar construction and combination of parts, substantially as hereinafter fully set forth, and specifically pointed out in the claims.

The object of my invention is to provide an improved seal-lock,which is especially adapted for use on railroad-cars while they are in transit, and which cannot be opened or tampered with without first breaking or otherwise injuring the seal.

A further object of my invention is to provide peculiar and novel locking devices which cannot be opened or picked without employing the proper keyfor their manipulation, and, further, to provide a lock which shall be simple, cheap, and thoroughly effective for the purposes designed.

In the accompanying drawings, Figure 1 is a perspective view of a seal-lock embodying my invention. Fig. 2 is a central vertical longitudinal sectional view thereof. Fig. 3 is a detached perspective view of the locking-bolt and the key applied thereto. showing the manner of withdrawing the bolt; and Fig. 4 is a detail view of the key.

Referring to the drawings, in which like letters of reference indicate corresponding parts in all the figures, A designates the lockcasing, made, preferably, rectangular in form, or approximately so, and having lugs or plates a at its rear end, either castintegral therewith or secured thereto.

B designates the hasp,which is pivoted at one end between the plates or lugs a, and is notched at its front end, as at b, the notched end of the hasp passing throughan opening, a, in one of the walls of the case A, near one end, and entering the chamber thereof. (See Fig. 2.) A sliding bolt, 0, is arranged .to move back and forth in the lock-chamber, one end thereof being notched, as at c, and the notched end thereof is normally pressed or kept in engagement with the notched end b of the hasp B,

(Model when the latter is fitted in the chamber by means of acoiled or other spring, D. One end of this spring bears against one of the walls of the case A, and the other end thereof bears againstashoulder, flange, lug,or other equivalent device, c", of thesliding bolt. The notched end of the bolt is beveled off, as shown, to permit the lower end of the hasp to force the bolt back and engage the notch therein, thus automatically locking the hasp by the spring-actuated sliding bolt, and the other'or rear end of said bolt is provided with a central longitudinal socket, e, a slot, 0', which opens into the socket, and a retaining-lug, e", for a purpose presently described. The key F has its web bent orcurved,as atf, and when the key is inserted in the look through a properly-shaped opening, f, in one ofitseud walls, the shank fits in the socket e, and the web slides in the slot 0 until it reaches a point in rear of the retaining-lug 6', when the key is turned so that the web abuts against the said retaining-lug,when the key is pulled outwardly to retract the bolt and withdraw the same from engagement with the notched end of the hasp, which can then be Withdrawn from the case.

G designates a seal,preferably of sheet metal, and having the name of the station stamped thereon from which the car starts. The ends of the seal are provided with openings 9, the upper one of which fits over the shank of the hasp, then passes or fits over the openingf' in the case, and is then bent under the lock and fits over a shoulder, arranged between the plates a and cast or formed integral with the lock-casing.

The operation of my invention is obvious from the foregoing description, taken in connection with the drawings. The hasp is autornatically locked with the sliding bolt by forcing the notched end of the former downwardly against the beveled face of the latter, which will yield and allow the notched ends to interlock. To open the lock, the seal is first removed from the shoulder g and the opening f exposed, when the key is introduced in the said opening, and the shank and web thereof fitting in the socket and slot, respectively, of the sliding locking-bolt. The key is forced in the socket of the bolt until it reaches the end thereof, when it is turned so that the web engages the retaining-lug e, after which the key is drawn outwardly of the lock to re tract the bolt from engagement with the hasp, which can then be released. I

My improved lock is simple, strong, and durable in construction, prevents egress to the locking-bolt without first removing or displacing the seal, can be manufactured and sold very cheaply, and is thoroughly effective for the purposes designed' Having thus fully described my invention, what I claim as new is- 1. In a seal-lock, the combination ofa casing, a hasp pivoted thereto, a sliding locking-bolt normally held in engagement with-the hasp to lock the same and having a socket, a slot opening into the same, and a retaining-lug, and a seal secured over the key-opening of the lock-casing, substantially as described.

2. A seal-lock comprising a casing having lugs a, a hasp pivoted thereto, a slidinglocking-bolt having a longitudinal socket and slot, and a retaining-lug, a spring for impelling the bolt, a seal secured over the key-opening of the casing, and a key having a web to engage the slot and retaining-lug of the locking bolt, substantially as described.

3. As an improved article of manufacture, a seal-lock comprising a casing having lugs a and a shoulder-catch, g, a hasp pivoted to the lugs, a locking-bolt arranged in the casing and having a longitudinal socket, e, a slot, 6, opening into the socket, and a retaining-lug, e, aspring, D, for impelling the bolt, aseal secured to the hasp, and the catch 9 over the key-opening of the casing, and a key having a curved web to engage the stop e to withdraw the bolt from engagement with the hasp, substantially as described.

Intestimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
